How To Implement FANET In NS3

To implement the flying ad-hoc networks (FANETs) in ns-3 consists to set up a network of unmanned aerial vehicles (UAVs) that can interrelate with each other wirelessly. Our developers can assist you in completing the implementation of your flying ad-hoc network.

Here are the procedures to walk through the basic set up for FANET simulation in ns-3 environment:

Step-by-Step Guide to Implement FANET in ns-3:

1. Set Up Your Development Environment

1. Install ns-3:
   • Follow the official ns-3 installation guide.
2. Install Required Modules:
   • Ensure you have all necessary ns-3 modules installed, such as WiFi and Mobility modules.

2. Create a Basic FANET Simulation Script

Here given below is the sample script to set up a basic FANET environment by using the ns-3:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/wifi-module.h”

#include “ns3/mobility-module.h”

#include “ns3/applications-module.h”

using namespace ns3;

NS_LOG_COMPONENT_DEFINE (“FANETSimulation”);

int main (int argc, char *argv[])

{

  // Set simulation parameters

  uint32_t numUAVs = 5;

  double simTime = 20.0; // Simulation time in seconds

  CommandLine cmd;

  cmd.AddValue(“numUAVs”, “Number of UAVs”, numUAVs);

  cmd.AddValue(“simTime”, “Simulation time”, simTime);

  cmd.Parse(argc, argv);

  // Create UAV nodes

  NodeContainer uavNodes;

  uavNodes.Create(numUAVs);

  // Configure WiFi for UAV communication

  WifiHelper wifi;

  wifi.SetStandard(WIFI_PHY_STANDARD_80211n_5GHZ);

  YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default();

  YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default();

  wifiPhy.SetChannel(wifiChannel.Create());

  WifiMacHelper wifiMac;

  wifiMac.SetType(“ns3::AdhocWifiMac”);

  NetDeviceContainer uavDevices;

  uavDevices = wifi.Install(wifiPhy, wifiMac, uavNodes);

  // Install the Internet stack on UAVs

  InternetStackHelper internet;

  internet.Install(uavNodes);

  // Assign IP addresses to UAV devices

  Ipv4AddressHelper ipv4;

  ipv4.SetBase(“10.1.1.0”, “255.255.255.0”);

  Ipv4InterfaceContainer uavInterfaces;

  uavInterfaces = ipv4.Assign(uavDevices);

  // Set up UAV mobility

  MobilityHelper mobility;

  Ptr<ListPositionAllocator> positionAlloc = CreateObject<ListPositionAllocator>();

  for (uint32_t i = 0; i < numUAVs; ++i)

  {

    positionAlloc->Add(Vector(0.0, i * 20.0, 20.0));

  }

  mobility.SetPositionAllocator(positionAlloc);

  mobility.SetMobilityModel(“ns3::ConstantVelocityMobilityModel”);

  mobility.Install(uavNodes);

  for (uint32_t i = 0; i < numUAVs; ++i)

  {

    Ptr<ConstantVelocityMobilityModel> mob = uavNodes.Get(i)->GetObject<ConstantVelocityMobilityModel>();

    mob->SetVelocity(Vector(5.0, 0.0, 0.0));

  }

  // Install applications (e.g., UDP echo)

  uint16_t port = 9;

  UdpEchoServerHelper echoServer(port);

  ApplicationContainer serverApps = echoServer.Install(uavNodes.Get(0));

  serverApps.Start(Seconds(1.0));

  serverApps.Stop(Seconds(simTime));

  UdpEchoClientHelper echoClient(uavInterfaces.GetAddress(0), port);

  echoClient.SetAttribute(“MaxPackets”, UintegerValue(100));

  echoClient.SetAttribute(“Interval”, TimeValue(Seconds(1.0)));

  echoClient.SetAttribute(“PacketSize”, UintegerValue(1024));

    ApplicationContainer clientApps = echoClient.Install(uavNodes.Get(numUAVs – 1));

  clientApps.Start(Seconds(2.0));

  clientApps.Stop(Seconds(simTime));

  // Enable tracing

  wifiPhy.EnablePcap(“fanet”, uavDevices);

  // Run the simulation

  Simulator::Stop(Seconds(simTime));

  Simulator::Run();

  Simulator::Destroy();

  return 0;

}

Explanation of the Script

Here is the explanation for the flying ad-hoc networks process script

1. Include Necessary Headers:
   • Include headers for ns-3 core, network, internet, WiFi, mobility, and applications modules.
2. Set Simulation Parameters:
   • Define the number of UAVs and simulation time.
3. Create UAV Nodes:
   • Create a container for UAV nodes.
4. Configure WiFi for UAV Communication:
   • Set up WiFi helper, physical layer, and MAC layer for ad-hoc communication.
5. Install Internet Stack:
   • Install the internet stack on UAV nodes.
6. Assign IP Addresses:
   • Assign IP addresses to UAV devices.
7. Set Up Mobility:
   • Define initial positions and constant velocity for UAVs using the ConstantVelocityMobilityModel.
8. Install Applications:
   • Install a simple UDP echo server on one UAV and a client on another UAV to demonstrate communication.
9. Enable Tracing:
   • Enable pcap tracing to capture packet traces for analysis.
10. Run the Simulation:
    • Set the simulation stop time, run the simulation, and clean up.

Further Enhancements

Here we provide the future improvements for flying ad-hoc networks

1. Advanced Mobility Models:
   • Implement more realistic mobility models, such as waypoint-based models or models based on real UAV flight patterns.
2. Routing Protocols:
   • Implement and evaluate different ad-hoc routing protocols such as AODV, DSDV, or OLSR.
3. Network Performance Metrics:
   • Collect and analyze performance metrics such as throughput, latency, packet delivery ratio, and network overhead.
4. Applications:
   • Implement more complex applications and communication patterns, such as video streaming or data aggregation.
5. Interference Modeling:
   • Model interference and evaluate its impact on network performance.
6. Fault Tolerance and Resilience:
   • Implement and evaluate fault tolerance mechanisms and resilience strategies for UAV communication.
